\section *{Preface}

\iris\ is a Matlab\raisebox{0.3em}{\tiny\textregistered} toolbox for macroeconomic modeling, developed by the \iris\ Solutions Team since 2001. The toolbox is free and open source, distributed under BSD license terms. The current version of \iris\ runs in Matlab R2014a or later; we though always recommend to update Matlab to the most recent version.

\iris\ has been designed as an integrated software package to support the development and operation of macroeconomic models and model-based analytical systems. To that end, the toolbox integrates core modeling functions (such as a flexible model file language, tools for simulation, estimation, forecasting, or model diagnostics) with supporting infrastructure (such as time series analysis, data management, or reporting) in a user-friendly command-oriented environment.

This document is a reference manual, not a user's guide or tutorial. Check out the website, \texttt{www.iris-toolbox.com}, for a number of tutorials covering a range of different topics.
